Kent JohnsonFortes lab, Portland Oregon
2Forensic Toxicology use Only
For Forensic Toxicology Use Only
Goal
• Development of an easy to use, interference free, less than 4 min
analysis method for ETG and ETS in urine
• LOQ, 100ng/mL or better
• Method validation using QC’s and real samples

LC/MS Method
• LC method
• Thermo Hypersil Gold 50 x 2.5 mm, 5u
• Mobile Phase A: 5mM Dihexylammonium acetate in LC DI H2O
• Mobile Phase B: 5mM Dihexylammonium acetate in CAN
• Mobile Phase C: ACN/IPA/Acetone = 45/45/10 v/v/v
• Column Temp: 50 Deg C
• Exactive MS method
• HESI source
• Full scan MS acquisition @ 100,000 Resolution
• External mass calibration
• Extract chromatogram for drugs of interest (m/z)@ better than 5ppm mass accuracy
• Confirm the identity using mass accuracy and RT
• Quantitate using peak area in the chromatogram

Conclusions
• Assay based on Exactive ultra high resolution MS coupled to LC system is
• Well suited for accurate analysis of ETG and ETS
• Analysis time of 4 min for ETG and ETS
• ETG LOQ = 100ng/mL, LOD = 25ng/mL
• ETS LOQ = 25ng/mL, LOD = 10ng/mL
• Exactive with a resolution of 100,000 offers >/= SRM selectivity (SRM data comparison
not shown)
• Very easy for method development and routine operation
• Can be multiplexed for even higher throughput
